Iphone storage problem

Force restart your device (press and hold both Side and Volume Down buttons, untill you see the Apple logo. When it appears, release both buttons, wait for your iphone to restart.

Then, please tell us what iOS version is currently running on that iP7+, sending us a screenshot showing the available space storage too (Settings>General>About... as already requested by Lawrence Finch in a previous post).

Thanks and regards

Your internal storage is not filled. Dear friend, this message is about your iCloud space, which has 5GB capacity

Hello,

Whatsapp back up into iCloud Drive so, if you have low storage capacity into iCloud you won't be able to back up and this issue will continue

buy iCloud storage or delete some files.

Cheers!

Go to Settings/General/About and see what is listed as Available.

That message doesn't make much sense, because there is no Storage & iCloud Usage setting in Settings/General. This may be a very old version of WhatsApp.

That looks like Whatsapp is sending that message, not iOS or Apple.

The problem is the message says to delete apps. There are no apps stored in iCloud. So it's clear that the WhatsApp message refers to storage on the phone.

Yes, please keep me informed.

Best of luck

The forced restart I asked you to perform wasn't a troubleshooting step. Just wanted to be sure that the info you're reading on Settings>General>About were correct.

I suggest that you restore that device to factory settings, installing a fresh copy of the most iOS recent version.

To do that, create a full backup of your iPhone using iTunes on a computer (if you don't have a computer, borrow one from your friends, or ask for help at an Apple Store or Authorized Service Provider), then use the steps provided in this support guide and, in the end, set your iP7+ up as new.

Restore your iPhone, iPad, or iPod to factory settings - Apple Support

When done, test it for a some hours, WITHOUT restoring data from your backup.

If everything is fine.... most likely something is wrong among your apps (and their related data).

I would try anyway to restore content from your previously made backup, but if the issue comes back again.... you need to re-perform the above procedure from the beginning.

Please let me know how it goes.

Regards

Giulio
